WEATHER-STRIP.

SPECIFICATION forming part-lof Letters Patent No. 274,158, dated March 20, 1883.

Application filed November 15, 1882. (No model.)

To alL 'whom tt may concern Be it known that I, CLARENCE F. WHIPPLE,

` of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Weather- Strips; and I do hereby declare that the following is a full, clear, and exact description vertical edges ot' a window-sash and to tue meeting-rails. Fig 2 isa perspective ofa fragment ofthe window-sash detached. Fig. 3 is a horizontal section of a Wintlowsash and frame having the improvement applied to the vertical edge ot' the sash. Figui shows the improvement applied to a parting-strip, and

Fig. 5 shows the same matters as Fig. 3, but illustrates the closing-stl ip folded `down at one v side of the central tongue.

Arepreseuts a Window-trame, and A a partingsttip. t

l5 is a groove formed in that surface ofthe frame or strip to which the closing strip is to be applied, and has a centrally-rountled tongue, b.

C is a looped closing-strip, ot' rubber or similar material, having its edges separated and set in two kerts out in the frame or partingstrip, one ou each side of the central tongue, b.

The closing-strip C normally projects beyond the edge or surface of the part to which it is app1ied,in order to be depressed when` in operation, as shown more clearlyin Figs. 3, 4, and 5. The effect of setting the edges of 'the looped closing-strip in two separate kert's some little distance apart is to make the said closing-strip more perfectly self-sustaining, and the interposed projecting tongue b supports said closing-strip near its bearing-point upon the opposing surface and insures an easy curve thereon when bent in the form t shown in Fig. 5, and thereby further prevents the closingstri-p from losing its elasticity. Said central tongue also has the effect of so supporting the closing-strip that the latter will commonly assume the form, when in use, shown in Figs. 3 and 4 or, in other words, to give said closing-strip a central bearing and an outward bend at each side ofthe tongue, wberebya wider bearing- J surface ot' the closiugstrip is obtained, with, of

course, a better result as to the general purpose -for which the closing-stripis employed. When properly applied to car-windows the closinglstrip supportrd by the tongue b, as shown, is

`found to be effective to prevent the sash from rattling, so that special springs for this purpose may be dispensed with.

I claim as my invention- The combination, with an opposing part, of a part, A or A', having the groove B, and a central rounded tongue, b, together with the flexible elastic closing-strip C, having its edges secured one at each side of the central tongue, b, substantially as described.

In testimony that I claim the foregoing as my invention I aiix my signature in presence of two witnesses.

CLARENCE F. WHIPPLE.
